Russian song from King of Queens episode?

ok for anyone who watches the show, its a season 5 episode where doug and carrie hire a bunch of ukrainian or russian workers to get the mold out of their house. While the guys are working, and slacking off, they're listening to this Russian, or Ukrainian song. It also plays when doug goes to their office to talk to them, and ends up drinking with them. It was a woman singing a kind of fast-paced folk song. or at least thats how it sounded to me. if anyone has any ideas, i would really appreciate it.
